Patent number: 11761654Abstract: A method which eliminates the need to remove environmentally-unsafe hydrochloro-fluorocarbons from an air conditioning system prior to the removal of the system's evaporator coil for cleaning is disclosed. The method also eliminates the cutting and soldering steps which must be conducted on the air conditioner system's copper refrigerant transport lines every time an evaporator coil is now removed for cleaning. The method utilizes a reversibly separable ball valve assembly unit affixed to each of the AC system's two refrigerant transport lines to achieve removal of refrigerant from the evaporator coil and its subsequent safe storage within other components of the air-conditioning system until the cleaned evaporator coil is reinstalled and the refrigerant's flow into and out of the cleaned evaporator is restored according to the disclosed method.Type: GrantFiled: November 12, 2020Date of Patent: September 19, 2023Inventor: Christian Ridao
